... equations on the right are As2 = λ 2s2. Subtracting the top equation on the right from the top equation on the left gives 2a = 12 so a = 6 and thus c = 8 while subtracting the bottom equation on the right from the bottom equation on the left gives 2b = −2 so b = −1 and thus d = 0, so we have recove ...

... C of A commute, we cannot immediately say that B 2 = C 2 gives (B + C)(B − C) = 0, etc. If we could do that, then since B and C are both positive-definite, we could say h(B + C)v, vi = hBv, vi + hCv, vi > 0 so B + C is positive-definite and, hence invertible. Thus, B − C = 0. But we cannot directly ...

... In this approach, it’s first recognized that Ax = b will have a solution only when b lies in the column space of A. In particular, a least squares solution is sought, in which only the portion of b that lies in that column space is allowed; this is defined as bc . Hence, the equation to be solved is ...
